1-[(Cyclo-propyl-meth-oxy)meth-yl]-5-ethyl-6-(4-methyl-benzyl)-1,2,3,4-tetra-hydro-pyrimidine-2,4-dione.

ABSTRACT: The pyrimidine ring in the title compound, C(19)H(24)N(2)O(3), is nearly planar (r.m.s. deviation = 0.008?Å); the C atom at the 5-position deviates by 0.054?(3)?Å from the mean plane and the C atom at the 6-position by 0.006?(3)?Å in the opposite direction. The benzene ring is approximately perpendicular to the pyrimidine ring [dihedral angle = 83.90?(10)°]. The amino group is hydrogen-bond donor to the exocyclic O atom at the 2-position of an adjacent mol-ecule, the hydrogen bond generating an inversion dimer. The cyclo-propyl ring is disordered over two sets of sites with the major component having 71.5?(4)% occupancy.

Project description:The asymmetric unit of the compound, C(20)H(26)N(2)O(5)·0.5C(2)H(5)OH, consists of two tetra-hydro-pyrimidine-2,4-dione mol-ecules and an ethanol mol-ecule. The pyrimidine rings are nearly planar (r.m.s. deviation = 0.006?Å in one mol-ecule and 0.009?Å in the other); the C atom at the 5-position deviates by 0.083?(3)?Å [0.064?(3)?Å in the second mol-ecule] from the mean plane and the C atom at the 6-position by 0.034?(3)?Å [0.082?(3)?Å in the second mol-ecule]. In each mol-ecule, the benzene ring is nearly perpendicular to the pyrimidine ring, the dihedral angle is 88.51?(8)° in one mol-ecule and 84.70?(8)° in the other. The amino group of each tetra-hydro-pyrimidine-2,4-dione mol-ecule is a hydrogen-bond donor to the exocyclic O atom at the 2-position of an adjacent mol-ecule, the hydrogen bond generating an inversion dimer in each case. The ethanol mol-ecule forms a hydrogen bond to the meth-oxy O atom of one of two independent mol-ecules.

Project description:The six-membered ring of the uracil part of the title compound, C(24)H(28)N(2)O(4), is nearly planar (r.m.s. deviation = 0.013?Å); the aromatic ring of the 3,5-dimethyl-benzyl substitutent is aligned at 85.4?(1)° with respect to this mean plane.

Project description:The asymmetric unit of the title compound, C(22)H(18)N(2)O(2), contains two independent mol-ecules, which differ in the orientations of the benzyl groups with respect to the planar (r.m.s. deviations of 0.031 and 0.020 Å) quinazoline-2,4-dione skeletons [dihedral angles of 73.97 (4) and 70.07 (4)° in the first mol-ecule and 75.63 (4) and 63.52 (3)° in the second]. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π interactions and aromatic π-π stacking inter-actions [centroid-centroid distance = 3.735 (2) Å].

Project description:The asymmetric unit of the title compound, C(20)H(18)F(2)N(2)O(2)S, contains four independent mol-ecules, two of which are paired into a dimer by way of two N-H⋯S hydrogen bonds.

In one mol-ecule, the carboxyl-ate O atoms, methyl-ene and methyl groups attached to the benzene ring are disordered between two positions in a 0.908 (3):0.092 (3) ratio. In two of the independent mol-ecules, the F and H atoms of the diflourophenyl ring are flip-flop disordered (i.e. by 180° about the C-C bond axis linking the ring to the rest of the molecule) in a 3:2 ratio. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
